Answer:
When evaluating synthetic blends, it's helpful to define the terms “synthetic blend” and “semi-synthetic”. Generally speaking, synthetic blends and semi-synthetic refer to the same thing: an oil that uses a combination of conventional and synthetic base oils in its formulation.
Explanation:
8 ∙ 10^-4 / 2 ∙ 10^2 = (8/2) ∙ ((10^-4)*(10^-2)) = <span>4 ∙ 10^-6</span>
Answer:
A = 5.6μs
B = 178.57kHz
C = 2.8μs
Explanation:
A. It takes ¼ of the period of the circuit before the total energy is converted from electrical energy in the capacitor to magnetic energy in the inductor.
t = T/4
T = 4*t
T = 4 * 1.4 = 5.6μs
B. f = 1/T
Frequency is the inverse of period
f = 1 / 5.6*10⁻⁶
f = 178571.4286Hz
f = 178.57kHz
C. time taken for maximum energy to occur is T/2
t = 5.6 / 2 = 2.8μs
Answer:
Noise level will be -18.2 watt
So option (b) will be correct answer
Explanation:
We have given sound intensity 
And threshold intensity 
( in question it is given as 
but its standard value is 
)
Now noise level 
So the noise level will be -18.2
So option (b) will be correct answer
